Specification of Letters Patent.

To all whom it may concern:

' Be it known that I, STANISLAS KoLoMYJ- SKI, a subject o-f'the Czar ofRussia, residing at Alexandrovsk, in the Empire of Bussia, have inventedcertain new and useful Improvements inv Valve-Gears for ReciprocatingSteam and other Engines,.of which the following is a specification.

This invention relates. to. an-improved valve-gear for steam and otherengines of the reciprocating type in which both. the admission andexhaust-ports are provided with'rotary valves that are located inspecial admission and exhaust-chambers, connected with the cylinder and.actuated simultaneously by eccentrics located outside of the cylinder,and for this purposetheinvention consists of a :steam or reother engineprovided with admission and exhaust-chambers communicating with. theworking cylinder and providedwith rotary valves for themlet andexhaust-ports, and compensating devicesfor holding the rotaryvalvestightly on the faces or seats ofthe admission or exhaust-chambers;andthe invention consists further 'ofcertain detailsof construction,

which will be fully described hereinafter and finally pointed out in theclaims.

The improved steam-engineisshown in the accompanying drawings, in whichsimilar letters of reference denote corresponding partsin all thefigures of the drawing, and in which Figure 1 represents averticallongitudinal section through the working steam or :other .cylinder, the.admission and exhaust chamhers and the rotary valves with theircompensating devices, Fig. 2 is a vertical transverse section, throughthe cylinder and the admission and exhaust-chambers, Fig. 3 is a detailvertical section, showing another form of compensator for the rotaryvalves,

=-haust.of thesteam to the cylinder. For arrangingthe rotary valves inproperunan- .ner on theworking cylinder 1, special admission-chambers 3,3 and exhaust-chambers 2,21 are arranged at opposite sidesof thecylinder. The admission and outletchambers are inclosed bycap-shapedcasings 5, 5 and 4, 4 which are connected by chan- 211615concentricallywit-h the cylinder respectively with ;the.admission-port 6and the eXhaustport 6 1 The rotary valves 8 which are arrangedin theadmission and exhaust- ;chambersi3, 3 and 2,2 are madeinithe form offiat disks, as shown. in Figs.- 4. :and 6, and are provided with anumber ofradiallyarranged openings 9. The sidewalls of the admission andexhaust-chambers are likewise provided withcorresponding openings 10 sothat hythe oscillations of the rotary .valves .8, theopenings 9 of thesame eitherregister with the openings in the admission and eX-haust-chambers, 3 and 2 so as to.-permit the supply of I thepressure-medium, or are placed out o t-register with the said openingsso as'to shut off the supply of the pressuremedium.

I For permittingthe free and unobstructed admission and exhaust of thesteam or other pressure-medium, theopenings 10 are pref- .eratbly.arranged at each side of the chamhers 3, 3 and 2, 2 so that on eachside-wall of said chambers arotary valve 8 hast-o. be employed, asshownclearlyin Fig. 1. The rotary valves 8 can either. be located .on theoutside ofsthe. admission-chambers 3, 3 as ;shown inv the upper. .andlower parts of Fig. 1, or on the inside of the same, as showndni Fig. 7.'J-lNhatever-betheposition ot-the rotary valves relatively to thefICQSzOlE seats; of the admission or exhaustchambersrespectively. 3, 3or 2, 2 the faces of. the vslide-valves i would be influenced.disadvantageously under the ..in fluence..o1:'. the .pressure-medium,that is tosay, theywouldinaone case .be liable to be moved away' fromthe faces, and in the .other case .1 pressed against the same. Forpreventing irregularities and untightnesses between the rotary valvesand their faces, compensating-devices have who employed which can -beconstructed in different ways, butwhich by preference are made intheform of pistons. The rotary valves 8 are connected by rods 11 with compensating-pistons 12 which are located at each side of the admission andexhaustchambers 2 and 2 as shown in Fig. 1, or at both sides of thechambers 2, 2 respectively 3, 3 as shown in Fig. 7. Each compensatingpiston 12 is guided in a special cylinder 13, but the inner cylindersfor the two pistons 12 which are located adjacent to each other betweenthe exhaust-ports are preferably united into one cylinder 13. Thepiston-cylinders 13 are provided with openings 14 back of the pistons orbetween the same for permitting the admission of the pressure-mediumwhich is either supplied from the working cylinder 1 in which case anequilibrium of pressure of the pressure-medium on the faces of therotary valves with the pressure in the working cylinder is obtained, orany other source of energy, such as compressed air, gas or any othermedium may be employed for producing the required degree ofcompensation. The pistons 12 are further acted upon by helical springs15, which serve for the purpose of pressing the rotary valves tightly onthe faces of the seats of the admission or exhaust chambers when thepressuremedium for producing compensation is not available, as forinstance, when the engine is to be started. The compensating devicesmay, however, also be located at one side of the admission orexhaust-chambers. Such an arrangement is shown in the upper and lowerparts of Fig. 1, and in detail in Fig. 3. In this case the compensatingpistons 12, 12 for the rotary valves of the respective admission orexhaust-chambers are located at the ends of piston-rods 11, 11 of whichthe piston-rods 11 is located within the tubular piston-rods 11 Betweenboth pistons, which are located in the cylinder 13, is arranged ahelical spring 15 and an opening 14 for admitting the pressure-mediumused to the compensating pistons so that by the same one piston isforced in outward and the other in inward direction, whereby thepressure on the faces of the rotary valves is equalized.

As for each admission, respectively, exhaust-chamber, eventually two ormore rotary valves may be used, it is necessary to actuate them bysuitable means, such as eccentrics and connecting-rods, from agoverning-shaft 16 by which every pair of rotary valves is actuated inthe same direction. This is accomplished, when the rotary valves arelocated as shown in Fig. 7 and in Figs. 5 and 6, at the inside of theadmission or exhaust-chambers, simply by providing the hubs of therotary valves at their adjacent faces with interlocking lugs 17 so thatwhen one valve is oscillated the other has to take part in theoscillating motion. This connection or coupling of the valves can,however, also be produced in the manner shown in Fig. 3, in which theinterior piston-rod 11 is provided with a key 18; which engages with acorresponding interior groove or keyway 20 at the inside of the tubularpiston-rod 11 so that while the pistons 12, 12 can be shiftedlongitudinallyt relatively to each other, at the moment when one of thepiston-rods is turned for oscillating the corresponding rotary valve,also the other piston-rod and with the same the other rotary valve hasto take part in the oscillating motion. In this form of connection ofthe piston-rods, the piston-rod 11 is preferably connected with thepiston 12 by means of a ball-bearing 19 shown in Fig. 3 so that thepiston 12 can be shifted longitudinally without participating in theoscillation of the piston-rod 11.
